Title: Apparatus for Loading Rows of Cuboidal Bags or Containers into a Collecting Receiver
IPC: B65B5/10
Filed: 1967-06-08
Abstract: 1,180,650. Packaging containers. SELFPACK G.m.b.H. 8 June, 1967 [16 June, 1966], No. 26612/67. Heading B8C. Apparatus for loading rows of cuboidal bags or other containers into a box comprises a gripping head movable in a vertical plane and provided with a relatively fixed plate forming a bottom jaw and a spring-biased plate forming an upper jaw for gripping the containers between them, and a device for advancing the box intermittently below the gripping head by the width of one row of containers. The gripping head is swung downwards to discharge the containers into the box. A number of containers P, Figs. 1, 3, is fed between the jaws 3, 4 of the gripper which is fixed to a bar 6 slidable in a guide 5. A cam 11 allows a spring 31, Fig. 3, to lower a rod 8, the upper end of which is pivotally mounted on the bar 6 and is restricted to movement along a slot 1<SP>1</SP> in a fixed plate 1. The upper jaw is held initially in the open position by a pin 22 on the plate 1 contacting a wedge fixed to the jaw. As the pivot of the rod 8 on the bar 6 moves along the slot 1, platform 4 descends, the guide 5 rotating about 7, to the chain-dotted position shown and slides relative to the guide 5 when the wedge on the jaw 3 contacts a stop 22A, causing it to release held cartons into a box B. Initially, the box B is supported on an incline 20 and against the first of a number of stops 16 on a cylinder 15. When the rod8 8 descends, an attached collar 9 lowers a pivotally attached rod 9A to operate a pawl and ratchet 14<SP>1</SP>, 14 to rotate the cylinder 15 to remove the first stop and bring the next into operation. The ratchet may be preset to advance by one or more teeth, so that one or more layers are deposited before the box B slides down to each succeeding stop. A magnetic or pneumatic control switch (not shown) is operated when the correct number of containers has been fed on to jaw 4 to release the gripping head 2, thereby initiating a loading operation. A fitted box B descends and depresses a plate 17 to tilt a lever 19 and deposit an empty box B supported on the lever on to the incline 20. The incline 20 is provided with guide rails adjustable to the width of the box B.

Title: Improvements in or relating to aeroplanes
IPC: B64C21/02
Filed: 1929-09-04
Abstract: 338,998. Beedle, H. W. Sept. 4, 1929. Planes, construction of; controlling.-For controlling the airflow about a wing, one or more openings are formed near the leading edge extending in the direction of the front spar and provided with pivoted valves on the upper or lower surface controlled automatically by a wind vane which acts to close the valves when a predetermined speed is reached. Fig. 1 shows an upwardly and rearwardly inclined passage closed at its lower end by a flap 4 pivoted at an intermediate point 5 near its leading edge. When the machine is at rest or flying at a low speed this valve is held open by a light spring, but as the speed increases it is closed by a, vane 6 connected thereto by an arm 7 and link 8. A light closing spring 9 may also be provided. The device may be formed as a unit to replace part of the main wing which is cut away to accommodate it. Alternatively, the passage may extend downwardly and rearwardly and be controlled by a valve which normally closes the upper surface of the wing and is pivoted at a point nearer to the trailing edge than the leading edge of the valve. This valve may be combined with another valve on the lower surface so that when the leading edge of the upper valve is raised that of the lower valve is depressed to admit air to the passage, both streams escaping through a comparatively restricted opening on the under surface at the rear edge of the passage.

Title: Improvements in and relating to the production of alkali cyanides
IPC: C01C3/10
Filed: 1931-05-22
Abstract: Sodium or other alkali cyanides are obtained by the absorption of gaseous hydrocyanic acid in the corresponding solid bicarbonate, or solid carbonate which has been produced by the calcination of bicarbonate at a temperature below 500  DEG  C.  A temperature of above 250 DEG  C., say 360 DEG  C., is preferably employed for the absorption reaction.  The hydrocyanic acid may be used in admixture with inert gases such as nitrogen, air, oxygen, or carbon monoxide. This mixture can be obtained by passing the inert gases through liquid hydrocyanic acid.  The process may be carried out continuously on a running tape, the sodium carbonate being supplied by a hopper at one end while hydrocyanic acid is supplied in countercurrent.  The process may also be carried out in a drum or cylindrical furnace. The apparatus or vessels employed are preferably constructed of aluminium.

Abstract: 465,265. Boots &c. UNITED SHOE MACHINERY CORPORATION. Oct. 3, 1935, No. 27269. Convention date, Oct. 16, 1934. [Classes 17 (i) and 17 (ii)] Sole-laying.-In cementing out-soles to welted shoes, the operation is performed in two stages, the first securing the sole in the neighbourhood of the inseam, and the second securing the welt to the outer part of the sole margin. Pyroxylin cement is, preferably, used at the inseam portion 22, and " pressureresponsive " cement, such as latex or rubber dissolved in benzol or naphtha, is used outside this area. After the cellulose derivative cement on the surface 22 has dried at least to the tacky stage, a softener having a high viscosity, such as that disclosed in Specification 406,030 or 408,245, is applied to this area, and the sole pressed against the shoe in a machine having a sole receiving pad of resilient but relatively firm or hard rubber or other suitable composition, there being, then, no substantial tendency to roll the welt and marginal portion of the sole toward the upper. The marginal portion of the sole is then progressively pressed against the welt in a machine of the kind described in Specification 7737 /09, [Class 17 (i)], having a work support 54 and a welt indenting roll 56; or in a welt beating machine having a reciprocating pounding tool 60 and a work support 62. In a modification, "pressure-responsive" cement may be used as the only sole-attaching medium. In another modification, the cement used at the margin of the sole may be inserted in the crevice between the welt and the sole margin after the sole has been secured to the inseam portion of the shoe.

Title: Method for fabricating a semiconductor device
IPC: H01L21/306
Filed: 1973-06-08
Abstract: 1418231 Semi-conductor devices INTERNATIONAL BUSINESS MACHINES CORP 8 June 1973 [30 June 1972] 27308/73 Heading H1K An integrated semi-conductor structure ineluding both metal and semi-conductor capacitive electrodes is made by a process involving five masking steps. The first masking step defines areas of a relatively thick oxide layer 4 (Fig. 10) which are removed and replaced by thinner oxide 5. Consecutive overall layers (6, 7, 8), Figs. 6, 7 (not shown), of silicon nitride, polycrystalline Si and SiO 2  are formed and the latter two layers are etched photolithographically, the oxide (8) serving as a mask for the polycrystalline Si so as to leave only portions 7<SP>1</SP> thereof on thin oxide areas 5. This constitutes the second masking step, and the remaining oxide (8) is then removed. The third masking step provides protectiion for areas of the nitride layer 6 lying on thin oxide areas 5 but not covered by polycrystalline Si 7<SP>1</SP>, this mask comprising photo-resist or, as shown in Fig. 10, oxide 9<SP>1</SP> defined by photolithography. The unprotected areas of thin oxide 5 are next etched through and B-diffusion is effected into the underlying Si substrate 1, as well as into the polycrystalline Si portions 7<SP>1</SP>. Reoxidation of the exposed Si, both of the substrate 1 and portion 7<SP>1</SP>, then takes place and a fourth masking step is used to open contact-making windows as necessary through to the diffused regions and to the polycrystalline portions 7<SP>1</SP>. After overall Al deposition a fifth and final masking step defines the desired conductor pattern. Fig. 14 illustrates a completed structure, including an IGFET having a metal gate 16, a Si-gate IGFET and a charge-coupled device having alternate metal and Si electrodes. The last-mentioned device may constitute a shift-register but Fig. 15 illustrates a random access storage cell having a diffused P+ bit line 12, a metal word line 19 part of which functions as a capacitive transfer gate for the storage cell, and a polycrystalline Si storage electrode 7<SP>1</SP>. Both the metal word line 19 and the polycrystalline electrode 7<SP>1</SP> extend over relatively thick oxide portions 13 as well as over the thinner gate oxide 5<SP>1</SP>.

Abstract: 504,444. Aeroplane toys. HORN, E. Sept. 19, 1938, No. 27319. [Class 132 (iii)] In a toy aircraft having spring driving-mechanism and means to eject a figure and attached parachute from the fuselage, the figure and parachute are released for ejection by means controlled by the running down of the spring driving-mechanism. The figure 7 carries, pivotally mounted on its feet, a member 10 engaging a slot 14 in a leaf spring 6, and a projection 12 on its chest engaging the underside of the cockpit 13. A thin loop spring 9 hinged to a projection 8 of the figure, engages a hook 11 on the member 10, and holds a folded parachute 15 against the back of the figure. A spring motor drives the propeller and landing wheels, so that the machine can run on a surface or fly suspended from a cord. As the spring 16 unwinds it rocks a lever 17 and through an arm 18 rocks the figure rearwardly to remove the projection 12 from engagement with the cockpit. The figure, thus released, is projected by the spring 6, the hook 11 releasing the spring 9 and the parachute 15 opening. In a modification, the arm 18 may be replaced by a flexible stay operated directly by the spring 16.

Title: Improvements in and relating to the ripening of viscose
Inventor: MORE JOHN WALTER
IPC: D01D1/06
Filed: 1957-08-30
Abstract: <PICT:0889009/IV (a)/1> In a process for adjusting the temperature in the continuous ripening of viscose, the latter is brought into intimate contact with an inert immiscible fluid heat transfer medium at a temperature which is different from that of the viscose and which has a specific gravity, when in liquid form, differing sufficiently from that of the viscose to facilitate its separation from the viscose at the completion of the temperature adjusting process.  The heat transfer medium may be kept in the liquid state throughout the process.  Its freezing point is preferably at least 20 DEG C. lower than the lowest temperature to be imparted to the viscose and its boiling point at least 20 DEG C. higher than the maximum temperature to be thus imparted.  The heating fluid may be the vapour of a liquid which condenses on contact with the viscose, thus releasing the latent heat of vaporization of the heating fluid to heat the viscose.  As shown, carbon tetrachloride from a thermostatically controlled reservoir 9 is pumped by the pump 8 at a temperature of 45 DEG C. and at a rate of one litre per minute through the tube 7 into the bottom of a vertical column 1, 33 inches in length and of 3 inches internal diameter.  The carbon tetrachloride flows through a perforated diffuser plate 10 up the column and, at a temperature of 42,5 DEG C., over a weir 13 into an overflow chamber 12 from which it flows through tube 14 back to the reservoir 9.  Viscose at 25,5 DEG C. is simultaneously pumped at the rate of 18 cc. per minute by a pump 5, tube 4 and horizontal perforated distributer ring 2 into the column 6 inches from its bottom.  The viscose is discharged from the top of the chamber 12 at a temperature of 40 DEG C. through the tube 11.
